.To all whom it may concern:

'Be it known that I, Gusr A. RIDDLE, a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in the Manufacture of Brick; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improved composition of matter for use in the manufacture of brick for building purposes and of a highly refractory nature; and it consists in the ingredients hereinafter set forth.

My composition of matter consists of the following ingredients in or about the proportions stated, viz: anister stone, (ground or pulvcrized,) ninc gallons; silicate of soda (li uid )one gallon; water, one gallon; "lvcerm twelve drops to each gallonof silicate 0 so a. These ingredients are thoroughly n-iingled or mixed in any suitable manner, as in a pug- 2 5 mill used fo working clay.

In using the above-named composition one gallon of silicate of soda, onolgallilm 0:] water;

- seven gallmr am two ve rm glycerin will manm'aclidre sixteen bricl zs of ordinary or standard size, which are molded 3c in roper form and dried by the aid of a gentle" ans uniform heat irTs't'iTd of burning in kilns,

as is the usual manner.

The silicate of soda acts as a binder for the ganister, the lycerin preventing or retardmg premature ardenin'g of the mixture when a large quantity is mixed atone time.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. The herein -described composition of matter for the manufacture of brick, consisting of ground or pulverized ganister stone, silicate of soda, water and glycerin, in or about the proportions stated.

2. The herein-described composition of matter for the manufacture of brick, consisting of round or pulverized ganister stone nine gallons, silicate of soda one gallon, water one gallon and glycerin twelve drops to each 50 jallon of silicate of soda, substantially at set forth.

In testimony whereof I aflix my signature in presence of two witnesses.
